Practically, you'll need to buy or build a water-cooling rig to get rid of the combined waste heat of both the peltier and the CPU. A decent power supplier must also be available -not only in terms of max. power, but also in terms of the current (amp) ratings for the PSU lines. Neoprene and dielectric (non-conductive, plastic-safe) grease will be needed as well to insulate the peltier, CPU and socket from condensation. You'll need to slip in a plate of copper (called a 'coldplate') in between the CPU and peltier so that the heat load/flux is well-distributed to the peltier -not so much as to cool better but to prevent damage to the peltier. Maybe you gotta get some long studs and nuts to mount the entire assembly (coldplate, peltier, waterblock) and take care not to exert too much force lest you crack the CPU core. Did I leave out anything? Oh, your electricity bills will be higher too.

they are amazing! no moving parts, and they do what they do! to find the hot and cold side of mine i turned up the juice on my train controler while holding the plastic. it was the strangest thing to have my thumb cold and my finger incresingly hot when their right next to each other. i didnt read the article on how they work so im going to be happy with my asumtion that its magic:)
